Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedar[1], in the family Lycopodiaceae, a family of fern-allies (see Pteridophyta). They are flowerless, vascular, terrestrial or epiphytic plants, with widely-branched, erect, prostrate or creeping stems, with small, simple, needle-like or scale-like leaves that cover the stem and branches thickly. The fertile leaves are arranged in cone-like strobilus. Specialized leaves (sporophylls) bear reniform spore-cases (sporangia) in the axils, which contain spores of one kind only. These club-shaped capsules give the genus its name.
Lycopods reproduce sexually by spores. The plant has an underground sexual phase that produces gametes, and this alternates in the life cycle with the spore-producing plant. The prothallium developed from the spore is a subterranean mass of tissue of considerable size and bears both the male and female organs (antheridium and archegonia). However, it is more common that they are distributed vegetatively through above or below ground rhizomes.
There are approximately 950 species, with 37 species widely distributed in temperate and tropical climates, though they are confined to mountains in the tropics.
The genera Diphasiastrum, Lycopodiella and Huperzia were once included within this genus, but are now recognized as being distinct. Some workers also segregate several more genera, including Dendrolycopodium for L. obscurum and related species, and Spinulum for L. annotinum and related species.
The spores of Lycopodium and Diphasiastrum species have been harvested and used economically as Lycopodium powder.
